‘The popular social blogging site Tumblr is hiring writers and editors to cover the world of Tumblr’

So meta my head imploded:

Chris Mohney, a senior vice president for content at BlackBook Media, will be the site’s editor in chief. Jessica Bennett, a senior writer and editor at Newsweek and The Daily Beast, will be the executive editor and, she said, a kind of Tumblr correspondent.

“Basically, if Tumblr were a city of 42 million,” Ms. Bennett said, referring to the number of Tumblr blogs that exist, “I’m trying to figure out how we cover the ideas, themes and people who live in it.”

Their work — both documenting the Tumblr service and marketing it to users — will appear on the Web site’s staff blog and on a separate part of tumblr.com that has not been set up yet, a Tumblr spokeswoman said Wednesday.
